Gabapentin is an anticonvulsant medication used to manage seizures and the pain associated with shingles. Gabapentin is a generic drug that is used to reduce depression. Gabapentin is available under the brand names Neurontin, Horizant, and Gralise. Insomnia is a sign of anxiety, and gabapentin has been shown to help individuals sleep easier.
Gabapentin: A Brief History
Considerable research on the effectiveness of gabapentin in the treatment of anxiety has been conducted over the past few decades. Gabapentin obtained final FDA clearance for advertising in the United States on December 30, 1993. Although it is only available as an anticonvulsant, it has also been used to relieve RLS, tremors, hot flashes, severe fatigue, and several psychiatric disorders.
A study published in The American Journal of Psychiatry in 1998 looked at many case studies and found that gabapentin for anxiety could be used in two ways: as an addictive drug for people with anxiety disorders or as a standalone treatment for severe anxiety disorders (most commonly panic disorder and generalized anxiety disorder).
Although case studies do not provide enough empirical evidence to support any drug use, they may catalyze more investigation. The efficacy of gabapentin is still being researched to see whether it can help people with a generalized anxiety disorder (GAD).
How Long Will It Take For Gabapentin To Control Anxiety Signs?
Gabapentin’s efficacy – and how long it takes to function – can differ significantly depending on the patient’s age. Numerous factors must be considered for drug use, including the nature of the person’s anxiety and the type of anxiety for which they are being treated.
The drug’s effectiveness is typically measured in weeks, but the person can profit from the treatment eventually. So, bear in mind that while gabapentin may be beneficial for certain people, it may not be for you.
If you or a family member is considering gabapentin as a treatment choice, consult with your doctor and determine together if this prescription drug is the safest and most appropriate course of treatment for anxiety.
Mechanism of Action
Although the precise mechanism of action with GABA receptors is unclear, scientists know that gabapentin crosses the blood-brain boundary and works on neurotransmitters. Gabapentin has a cyclohexyl group in its chemical composition, similar to that of the neurotransmitter GABA.
Despite its structural similarity to GABA, it does not attach to GABA receptors and does not affect GABA synthesis or absorption. Gabapentin inhibits the secretion of dopaminergic neurons in the presynaptic region by classifying propensity for functional groups throughout the brain that corresponds to the existence of voltage-gated calcium channels, particularly alpha-2-delta-1.
Despite the lack of evidence for damaging effect at the serotonin, dopamine, benzodiazepine, or histamine sites, gabapentin has been shown to increase blood serotonin levels in healthy subjects in studies significantly.
Gabapentin has a 5- to 7-hour removal half-life, and it requires the body two days to remove it from its system. Gabapentin’s moderate side-effect profile is one of its advantages. Fatigue, dizziness, and headache are the most common symptoms.
